(This explanation is the same I sent to someone who previously also had the same issues of not being able to understand the recent chaps)
It's originally stated that wang yi lost his memories about being a system and could only recall the life he had when the bus accident occured thus making him a 'host' to become the villain in every world he hopped on.While the cat was his guide system to ensure he does his role of being a villain perfectly.
There's also an explanation that the cat system was originally an extra system that used to follow system wang yi while 'x' was the host.
'It' (the antagonist that's yet to be revealed) was eliminating errors or anomalies that aren't supposed to interfere with the different worlds.
It was shown in chap. 110 that wang yi as a system, deleted his existence and memory so that cat system would survive as an official system. And that cat should pretend not to remember his existence.
'X' made a promise to wang yi that he would be with him forever thus world hopping every world that wang yi lands unto. While 'it' is supposedly following them trying to eliminate 'X' as he is an anomaly.
The cat system was supposed to be harsher with wang yi, and that wang yi was supposed to have gotten more harsher punishments (like that scene where wang yi's identity was found out by 'x' thus resulting in an electrocution) but only lessened the pain (cat didn't want to punish wang yi but if cat system didn't punish wang yi, they would be immediately found out by 'it').
Cat system wanted wang yi to stay happy even if he knows that it would only result in his own destruction.
